Zur Funktion der Aktivatoren im technischen Ammoniak‐Katalysator

R. Krabetz, +1 more
- 07 Apr 1965 - 
TL;DR: In this paper, the katalytische Aktivitat von ammoniakkatalysatoren verschiedener Zusammensetzung in Zusammenhang zu bringen mit ihrer inneren Oberflache, ihrem Porengefuge and ihr Fahigkeit, Kohlenmonoxyd and Kohlendioxyd zu chemisorbieren.
Journal ArticleDOI

The Function of the promotors in the Technical Ammonia Catalyst

R. Krabetz, +1 more
- 01 Apr 1965 - 
TL;DR: In this article, a phenomenological description of the relationship between the catalytic activity and the distribution of the promotors in the reduced ammonia catalyst is given, and a series of catalysts whose compositions were gradually brought closer to that of technical ammonia catalysts by the addition to iron of one new activator (Al2O3, K2O, CaO, MgO, SiO2) at a time.
Journal ArticleDOI

Zur Wirkung des Kaliums im Ammoniakkatalysator I. Kinetik der Synthese an ein- und zweifach aktivierten Katalysatoren

R. Krabetz, +1 more
TL;DR: The validity of the rate equations, due to Temkin and Pyshew and to Ozaki, Taylor and Boudart, for the ammonia synthesis on singly or doubly activated iron catalysts has been tested by kinetic measurements at atmospheric pressure and in the temperature range from 280 to 370 °C as discussed by the authors.
Journal ArticleDOI

Zur Wirkung des Kaliums im Ammoniakkatalysator II. NH3-Synthese an schwefelvergifteten Katalysatoren

R. Krabetz, +1 more
TL;DR: Ozaki, Taylor and Boudart as discussed by the authors showed that the effect of the adsorption of sulphur is compared with that of the chemisorption (oxygen) of oxygen.

Zur Bedeutung der Tonerde für die Struktur des Ammoniakkatalysators

TL;DR: In this paper, an unreduzierten Zustand des Kontaktes bildet die Tonerde als Spinell FeO · Al2O3 Mischkristalle with dem================== �
